How to Make It
Heat grill to medium-high. Brush the zucchini with 1 teaspoon of the oil and grill until tender, 5 to 7 minutes per side.
Cut the zucchini into 1-inch pieces and toss in a large bowl with the scallions, lemon juice, red pepper, the remaining tablespoon of oil, and ¾ teaspoon salt. Serve at room temperature.
